My patent application-relates to clamping devices for use-upon cables,cable ways, guy lines; and infany and all places where it is founddesirable to placea clamp to which blocks, tackle, guy lines, and thelike may be attached or to be used as a splicing I One of the objects ofmy deviceis to provide a clamping devicethatmay be placed on thelinewith the line in place without the removal of the line orthe'loosening of one end of the line. V

a A further object of my device resides in applied to the cable; orline; a piece at a time and "the clamping mechanism be applied withouttheremoval 'of the line, or the loosening of one end of the lin'e.

A further object of my device resides in a structure adapted for beingattached to a cable way, guy'line or sky line in place and to which maybe attached any desired block or tackle, 'qui'ckly and Without undueloss oftime.

. Referring to the mechanism illustrated in Figs. 1, 2, 3 and 4, asthe'same applies to single ended clamps in'w-h-ich a split body member 1and 2, is formed of independent units having a central section '3,hingedly secured to one of the side bodyv members by any suitablefastening means. Each ofthe side body members 1 and 2. formsubstantially a vhalfcylinder 4'and 5, with the hinged member 3, havingsubstantially. a half cylinder '6 and 7 disposedat oppositely disposedsides, so that if a splice is to be ffiormed,-as illustrated in Fig. 1,the main line 8 maybe passed through one of the sides .ofthe clamp andthe return end 9 may be passed through the oppositely-disposed side ofthe clamp to form an eye 10 Within lthe-bi ht. 'Bodymembers 1 and .2 arethreaded on their outer periphery to which the male end 37 may bethreaded. To prevent 6 the slippageyof the central. section "longi- 3tudina'zlly of the line, a lug 12 outwardly extendsfrom the side of thecentral section.

The lug being adapted to engage within the receiving recess 13, disposedin one of the side sections. The side body elements 1 and 2 are hingedlysecured together by a hinged 7 link 14 that is disposed therebetween,and

'the same is held in :placeby journal pins 15 and 16. :VVhere the doubleendedclamp is 'to be diormed, thesame may be made as illustrated inFigs. v5 and 6,.wherein the central side wall body members 17 and 18 arehingedlv secured together and wherein male threaded sections 37 areadapted to threaded engagement with the oppositely disposed ends of theside sections 17 and 18. The central section 21 being adapted to engageoppositely disposed sides OfpthG cables 22 and 23 being disposedtherebetween.

A modified form of the clamp may be made, as illustrated in Figs. 7 and'8 where-. -in'the central side wall sections 24 and 25- haveuniformlytapering, oppositely disposed ends, to form .aclampingd'evicefor a single cable to be passed therebetween. Male clamping collars 26;and 27 are adapted to being driven upon oppositely disposed ends 7ofthe clamp and when a suflicient pressure has been developed between:the side wall members 24 and25 and the cable '28 to be passedtherebetween the same are held in relatively fixed position relative tothe .side wall members 24 and 25 by the locking device 29. 'A slot 30 islongitudinally disposed on the outer surface of eachof the collars 26and 27 5 with lockingv notches 31 ment within the locking notches sothat when the collars are driven home on the clamping device it ismaintained in position through thelockinghook engaging the lookingnotches. I

.lVhere the clamping device is to be used on logging operations, or onships tackle, the device may be made ,as illustrated" in Figs. 9,10,11., 12 and 13, and wherein the central sections 34 and ,35' areadaptedzto -:coact with each other and wherein the side wall member .34has a central ri'b 36. down- A wardly extending from \the horizontalcentral line of the body portion 34. After'the bodyvmember-34 is placedupon the-line, as illustrated in Fig. 10 the adjacent section is thenput in'iplace within the yoke 36. The A female engaging .endsect-ions 37and 38 which are made split, as illustratedi-n Fig. 13, are then placedabout the threaded end sections of the central members, whenp'laced*thereupon, the locking pins 39 are then in-3 sorted-- within the freeend section of the supporting block 43 is then raised :to positiongthesame being hingedly supported to the yoke by a journalpin 44 after whichthe-supportingblock is maintained in posi- .tion through the locking pin45. The supporting block 43 may have any suitable supporting meansassociated therewith as a ring 7 '46 into which .ayoke 47 is-made toengage for supporting any suitable tackle gear as .a

' block 48.

. While the form of :mechanism .herein shown :and described is admirably-adapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to con- ;fine the invention to theforms oiembodiments herein shownyand described, as it is susceptible ofvembodiment in various other 3120 forms, all coming within the scopeofthe claims which follow:

WhatIclaimis: I

11. Ina device of the class described, the combination of male .andfemale coin-S ing i clamping elements, the male element comprising twosections hingedlysecuredwith each other beingthreaded their outerperiphcry, ;a separator hingedly disposed longitudinally therebetweenhaving a concaved no surface disposed on its oppositely disposed sidesand male elements having means hingedly disposed thereon for permittingtheir placement about the -male element Without disturbing the cable.

2. In a device of the class described, the combination of male andfemale clamping elements in threaded relationship "with each s other,the male element comprising a plurality of semi-cylindrical"unitshingedly connected with each other and a separator bin edly disposedtherebetweenadapted for maliing two complete cylinders when in closedposition, threads disposed on their outer periphery, meansdisposedwithin two units for the preventing of longitudinal slippage of theseparator section when clamped on a line, the male elements compris ng aplurality of units hingedly connected with each other, threads disposedon their inner walls, and means for locking the said units when the malesections are placed in position for threading together the male and faceeach having a hinged opening, and

means for locking these hinged openings after placement of the femalesections about the male section.
